or CHICAGO, ILLINOIS, A COREOBATION or DELAWARE REFRIGERATOR-OAR-DOOR FASTENER Application filed February This invention relates to door operating mechanism. An object of the invention is to provide a door operating mechanism including a pair of reciprocable operating elements arranged to be reciprocated in opposite directions, and beingmounted for rotation as well as'reciprocable movement, said operating .members being adapted to cooperate with keeper means aflixed to the door frame, whereby reciprocation of said operating elements in opposite directions in one position of the mechanism, effects closing movement of the door, and reciprocation of said members in opposite directions in another position of the mechanism after rotation of said operating elements with respect to said keepers, efiects opening movement of said door.

Other and further objects and advantages of the invention will more clearly appear from the description and claims hereinafter following.

In the drawings forming a part of this specification Fig. 1 is a side elevation of a portion of a refrigerator car, showin my improvements in conne'ction therewith. Fig. 2 is a vertical sectional View, on an enlarged scale and partly broken away, corresponding substantially to the line 22,-Fig. 1, showing 0 the operating eleme'nts'in the position which they occupy when the door is closed. Fig. 3 is a vertical sectional, fragmentary View on an enlarged scale, showing the upper portion of the actuating element and keeper means, whenthe actuating element has been rotated to its position at the inception of the door opening operation; and Fig. 4 is a horizontal fragmentary sectional view of the lower end of they actuating element, substantially on the means in top plan.

In said drawings, the side of the car is shown as provided with a door frame 10 and two pivoted doors 11 and 12 having meeting r beveled-edges in-the usual manner; The customary -insulation or packing is employed between the meeting edges of the doors and I door frame, and also between the meeting edges-of the doors themselves; The doors 11 and -12'aremonntedfor swinging movement per and lower power line of Fig. 1, and "showingthe keeper 5, 1926.

about vertical axes, being supported by suitable 'hinges 1313.

As shown, the improved door operating mechanism comprises broadly, a two part operating mechanism A, provided with end actuating members B-B; an operating lgangle C; and upper and lower keepers The operating mechanism Aincludes uptransmitting members '7 14 and 15, the lower transmitting member 15 having its inner end pivotally connected to the end portion of the operatinghandle C, as indicated at 16, and the inner end ofthe power transmitting member 1 1 is pivotally connected to the handle C at a point spaced inwardly from the end of the handle and from the pivotal connection 16 as indicated at 17, the handle C having an offset portion 18 providing a hand grip. The transmitting member 15 is pivotallyconnected at its lower end to the actuating member B as indicated at 19, and the transmitting member 14L is pivotally connected at its upper end to the Zipper actuating member B as indicated at O. Y The actuating members B B, connected to the upper and lower extremities of the transmitting links 14 and 15 are of similar construction. Each of the same includes a cylindrical section 20, which is slidably and rotatably mounted in a supporting guide bracket 21 affixed adjacent the edge of, the door, the bracket 21 being provided. with a central portion 22 having a cylindrical bore 23 therein to accommodate the actuating member B, the bracket 21 being provided with flanges 24 throughwhich extend suitable securing bolts 25." The actuating member B is adapted; for slidable androtative movement with respect to said guide member, the inward sliding movement offthe member B being limited by the shoulder or collar 26 formed on said member. The outer end por- I tion of the actuating member B is provided with a wedge or cam face 27, adapted to cooperate with wedge surfaces of the keepers D D as hereinafter more fully described. Both oftheactuating members B-B, and both of the guide brackets 2121-are similar The keepers DD are two in number, and of similar construction, one of thesame bein g arranged adjacent the. outer end of each of the actuating portions BB. The upper keeper'D comprises avcentral socket portion 47, and flange portions 28 at eachside of the socket portion, through which securing bolts 29 extend. The socket portion is formed so as to provide an inner wedge or cam surface 30 adapted to be engaged by the wedge surface 27 of the associated actuating member B when closingthe door, the end portion 31 of the outer wall of the socket portion providing an inclined 'wedging or cam surface adapted to be-enga-ged by the cam surface 27 of the actuating member B when the door is being forced to open position. The lower keeper D is similar in all respects to that justdescribed and similar reference characters will be used to designate like parts. In addition the lower keeper D is provided with a portion 82 extending toward the left hand door, uponwhich is pivotally mounted a latch 33, which is adapted to be turned into engagement with a wear plate 34 secured to the lower right hand corner of the door 11, when said dooris closed.

Suitable locking and sealing mechanism 85.0f a common form may be associated with the handleC and operated to secure the handle to the door 11 when the doors are in closed position. i p In the operation of my'improved device,

assuming the doors to be closed, when it is desired to open the same, the handle C is I first released from the sealing and locking mechanism 35, after which the handle C is moved downwardlyin the direction of the arrow as shown in Fig. 1, which due to toggle action of the connections of the links i l and 15 with the handle G will operate to cause inward movement of the imtiiating members B.B to release the same from the keepers" D, after which the transmitting members l l and 15'Wlll be rotatedto effect rotation of the actuatingmembers B to such an extent as to bringthe same to the position shown in Fig. 3, after which the handle G will be elevated" to the position shown in dotted lines in Fig. 1, resulting in outward projection of the transmitting links 14 and 15, and consequently of the'actuating members B-B associated therewith, the wedge" surfaces 27-2701 the actuatingmembers 'B.B-bearin 'uaon the outercam surfaces :al of the keepers DD, forcing the door in anopening direction a sufficient d stance to clear the insulation between the edges there of, after which tne door 12 may be swung to fully open position, and the door 11 'may' be opened by turning the latch 33 to inoperative position. It will be noted that during this action, should one or the other of the actuating members B become stuck in its related keeper, when the free actuating element B has travelled to a sufiicient extent to bring the collar 26 into engagement with the guide bracket, the entire power exerted will be brought to bear against the keeper which is stuck, so that the actuating elements may be always properly disengaged.

When it is desired to close the doors, the door 11 is'first'swung nearly closed by hand, after which the pivoted latch 33 may be turned into engagii position to hold the door 11 closed.v The door 12 is then swung partially closed, and the handle C may be depressed from thedotted line position, and rotated in a clockwise direction until the wedge sur means 35.

W'hile I have herein shown and described what I now consider the preferred manner of carryingout my invention, the same is merely illustrative, and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
